Installation

Clone into ComfyUI/custom_nodes:

cd ComfyUI/custom_nodes
git clone https://github.com/zwglass/ComfyUI-GPUStatusPanel.git

Install dependencies:

pip install -r requirements.txt

Restart ComfyUI.

Supported Platforms

| Platform | Backend | GPU Util | VRAM | Temperature | Power | |----------|---------|----------|------|-------------|-------| | NVIDIA GPU | NVML | ✅ | ✅ | ✅ | ✅ | | NVIDIA GPU | torch.cuda | ❌ | ✅ | ❌ | ❌ | | Apple Silicon | MPS | ❌ | ✅* | ❌ | ❌ | | CPU | psutil | ✅ | ✅ | ❌ | ❌ |

*MPS shows system memory as GPU memory reference

Usage

Once installed and ComfyUI is restarted, a GPU status panel will appear in the top-right corner of the interface:

• Drag the header to move the panel
• Click − to minimize/restore the panel
• Click × to close the panel (refresh page to restore)

API

The plugin exposes a simple HTTP endpoint:

GET /gpu_status

Response:
